List of World Heritage Sites in Laos

The United Nations Educational, Scientific and Cultural Organization (UNESCO) designates World Heritage Sites of outstanding universal value to cultural or natural heritage which have been nominated by countries which are signatories to the UNESCO World Heritage Convention, established in 1972. Cultural heritage consists of monuments (such as architectural works, monumental sculptures, or inscriptions), groups of buildings, and sites (including archaeological sites). Natural features (consisting of physical and biological formations), geological and physiographical formations (including habitats of threatened species of animals and plants), and natural sites which are important from the point of view of science, conservation or natural beauty, are defined as natural heritage. Laos, officially the Lao People's Democratic Republic, ratified the convention on 20 March 1987.

, Laos has three sites on the list. The town of Luang Prabang was listed in 1995, Vat Phou in 2001, and the Plain of Jars in 2019. All three sites are cultural. In addition, Laos has two sites on its tentative list.

World Heritage Sites
UNESCO lists sites under ten criteria; each entry must meet at least one of the criteria. Criteria i through vi are cultural, and vii through x are natural.

Tentative list
In addition to sites inscribed on the World Heritage List, member states can maintain a list of tentative sites that they may consider for nomination. Nominations for the World Heritage List are only accepted if the site was previously listed on the tentative list. , Laos lists two properties on its tentative list.
